Patented Mar. 1, 1932 HARVEY B. JORDAN, OF CLEVELAND, OHIO TUYERE STOCK BRIDLE Application filed June 9, 1930. Serial No. 459,904.

This invention relates to bridles for blast furnace tuyere stocks and the primary object of the same is to provide a deviceof this class which will positively retain the tuyere stock and blow pipe in position relatively to the furnace tuyere and which at the same time is of a simplified construction and easily and quickly applied to and adjusted and released from the tuyere stock.

With the foregoing and other objects and advantages in view the invention consists in the preferred construction and arrangement of the several parts which will be more fully described and claimed.

In the drawings:

Figure 1 is a view in side elevation of a blast furnace tuyere stock and associated parts showin the improved bridle applied in position relative to said stock.

Figure 2 is a sectional plan view taken on the line II-II of Figure 1.

Figures 3 and 4 are fragmentary detail views of parts of the bridle.

The improved bridle may be used alone or as an auxiliary or safety bridle in conjunction with the bridles commonly used for tuyere stocks, its simplicity and cheapness of construction enabling such cooperative use with but slight additional cost. Experience has demonstrated that its use as a safety vbridle in conjunction with a main bridle is of considerable value as in many instances parts of the main bridle break or its connectionsgive way and serious consequences result.

Referring to the drawings, the numeral 5 designates the wall of a furnace having positioned therein in the usual manner a tuyere 6 and tuyere cooler 7 a blow pipe 8 projecting into thetuyere and connecting with the usual tuyere stock 9, goose neck 10 and bustle pipe 12. The outer curved wall of the tuyere' stock is provided with the usual peep-hole neck or extension 13 formed with an opening for inspection and cleaning out the tuyere,

which opening is closed by the tuyere cap or wicket 14.

The improved bridle, in its preferred con- PA T OFFICE struction, comprises a yoke 15 adapted to the outer curvature or bend of the tuyere stock immediately above the neck or extension 13, the ends of said yoke being bent outwardly and formed with openings to receive the slotted ends of side rods 16 which are held in place by tapered keys 17. Lugs 18 are securely anchored or fastened to the metal shell of the furnace hearth and each rod 16 has the opposite end thereof bent into the form of a hook which is passed through an eye formed in'one of said lugs. The yoke 15 is thus securely anchored to the hearth jacket, and the tuyere stock 9 and blow pipe8 are held in position against displacement due to furnace blast pressure.

The slots in the ends of the rods 16 and the tapered keys 17 cooperate to provide a simple I and effective means of tightening or adjusting the bridle assembly, and conversely, the

yoke 15 may be easily and quickly released movably securing the yoke to the tuyere jacket.

2.-A bridle for securing tuyere stocks to the hearth jacket of a blast furnace, said tuyere stocks each having an outer curved wall, said bridle comprisinga yoke member adapted to engage the outer curved wall of a 'tuyere stock and means for detachably securing the yoke to the hearth jacket, said means 9 comprising connecting rods having slotted ends passing through the extremities of the yoke and adj ustably keyed thereto by keys extercilding through the slots in the ends of said ro s.

3. A bridle for securing tuyre stocks to the hearth jacket of blast furnaces, said 5 tuyere stocks each having an outer curved wall said bridle comprising a yoke member adapted to fit around the outer curved wall of a tuyere stock and being formed with outwardly bent slotted extremities and means for securing the yoke relative to the hearth jacket, said means comprising anchor lugs and connecting rods hooked into said lugs at one end and slotted at their opposite ends, said slotted ends passing through the slotted extremities of the yoke and being adj ustably keyed thereto by keys extending through the slots in the endsof said rods.

In testimony whereof, I have hereunto set my hand. HARVEY B; JORDAN.
